[Every week, IndieGames.com: The Weblog co-editor Tim W. will be summing up some of the top free-to-download and commercial indie games from the last seven days on his sister 'state of indie' weblog.]

This week on 'Best Of Indie Games', we take a look at some of the top independent PC Flash/downloadable titles released over this last week.

The goodies in this edition include a 2D platformer designed as an obstacle course, a Metroid-like exploration game, an homage to the great Oregon Trail, and a pair of Unreal Engine-based indie games.

Here's the highlights from the last seven days:

Game Pick: 'Training Set' (John Nesky, browser)
"Training Set is a 2D platformer that features unconventional controls to learn about, where the only way you can acquire new skills is by conversing with spooky silhoutted characters for some useful wisdom and advice. There's no text to read and instructions to play are near non-existent, but the game does provide just enough clues for you to overcome one challenge after another at a very steady pace."

Game Pick: 'Escape from the Underworld' (Banov, freeware)
"Escape from the Underworld is the story of a dark angel's fall from glory, and consequent rise from the underworld. With all your powers taken by heavenly beings, you're left to roam the depths of Hell, building your strength back up so you exact your revenge."

Game Pick: 'Organ Trail' (The Men Who Wear Many Hats, browser)
"Organ Trail is a zombie homage to the classic Oregon Trail game. Amidst a zombie outbreak, a small band of friends grab a station wagon, stock up on supplies and hit the road in an attempt to reach a safezone all the way across America."

Game Pick: 'Magnesian' (PineApple Fish, freeware)
"Magnesian is a side-scrolling platform-puzzler game in which the player uses magnetic abilities to move blocks and launch their character around. Tons of neat ideas to explore, and it's very pretty too."

Game Pick: 'Sp.A.I' (No Comment, freeware)
"Developed by a team of students at Queensland’s University of Technology in Australia, Sp.A.I sees you taking control of Aiva, a virtual world infiltrator, as she brings down firewalls via increasing difficult block puzzles, swims through the innards of the program dodging lasers and security bots, and decrypting files by entering them and navigating her way to the core."
